if bitcoin can be used throughout the world it will create a balance of the business world, because there will be no more inflation and no currency that always controls the other currencies. the business world will be truly stable and people will be greatly facilitated if they want to sell goods between countries.
if this happens, then the level of trust in fiat will decrease and many people will avoid taxes with bitcoin in each case, especially payments.
inflation will be far greater than expected. Subjectivity refers to the same direction of economic media and actually this would be very good if regulations had been implemented, but its popularity would not be as big as before the regulation.
